Die Ausführung des geschilderten Verfahrens stellt sich folgendermassen dar : Auf eine ebene Fläche, z. B. eine Platte, wird Chromatgelatine aufgegossen, die Strichzeichnung mit der Bildseite nach unten aufgelegt und belichtet. Nun bedeckt man die ginze Fläche mit fetter Druck farbe und entwickelt die Chromgelatinekopie durch Einlegen in kaltes Wasser. Auf den den
EMI2.1
Aufgiessen einer alkoholischen Lösung von braunem, ungebleichten Schellack setzt sich dieser an den Strichstellen auf der Platte an, an den übrigen Stellen lagert er sich auf die fette Farbschiebt auf.
Mit dieser wird der Schellack mechanisch weggeschafft, wenn die Platte in ein Fettlösungsmittel wie Petroleum, Terpentinöl oder dergl. eingelegt wird, wogegen die auf der Platte haftenden Schellackteile unverändert bleiben. Die neben ihnen noch vorhandenen wasserunlös- lichen Reste der Chromatschicht werden durch Einbringen der Platte in ein saures oder alkalisches

Wendung verschiedener Bäder, so nimmt man bei Aluminiumplatten verdünnte Salpetersäure. bei Zinkplatten verdünnte Phosphorsäure, bei Glasplatten Wasserglaslösung u. s. f.

The execution of the described method is as follows: On a flat surface, e.g. B. a plate, is poured chromate gelatin, the line drawing is placed face down and exposed. Now cover the entire surface with bold printing ink and develop the chrome gelatine copy by placing it in cold water. On the
EMI2.1
Pouring on an alcoholic solution of brown, unbleached shellac, it attaches itself to the line areas on the plate, at the other areas it attaches to the fat color slide.
With this, the shellac is removed mechanically when the record is placed in a fat solvent such as petroleum, turpentine oil or the like, whereas the shellac parts adhering to the record remain unchanged. The water-insoluble residues of the chromate layer that are still present next to them are converted into an acidic or alkaline layer by placing the plate in an acidic or alkaline layer
EMI2.2
If different baths are used, dilute nitric acid is used for aluminum plates. For zinc plates, dilute phosphoric acid, for glass plates, water glass solution, etc. s. f.
